The way to get had up for riding an elephant (6)
I believe the answer is:
howdah
'riding an elephant' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'the way to get had up' is the wordplay.
'the way to' becomes 'how' (ie how to do something).
'get' says to put letters next to each other.
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'had' in reverse letter order is 'dah'.
'how'+'dah'='HOWDAH'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for howdah that I've seen before include "Seat on an elephant's back" , "Elephant rider's seat" , "Elephant's back pavilion" , "Canopied elephant seat" , "Elephant rider's chair" .)
